Questione giuridica chiave
Whether the appeal was admissible against revocation of settlement and refusal of residence permits
Decisione estratta
The appeal was admissible as to the revocation of the settlement permit and, for the spouse and children, insofar as they could rely on family reunification rights; the challenge to the first-instance cantonal decision was inadmissible.
Motivazione estratta
Revocation decisions fall within the scope of administrative-law appeal; the wife and minor children could invoke a statutory right to residence only if the husband had a valid settlement permit. The request to attack the original service decision was barred by devolutive effect.
